I believe the answer is:

oklahoman

I'm a little stuck... Click here to teach me more about this clue!

'tulsan?' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'monk with a halo converted' is the wordplay.
'with' says to put letters next to each other.
'converted' indicates an anagram.
'monk'+'a'+'halo'='monkahalo'
'monkahalo' anagrammed gives 'OKLAHOMAN'.

Can you help me to learn more?

(Other definitions for oklahoman that I've seen before include "US resident" , "American" , "from Tulsa?" .)

I've seen this clue in The Telegraph.
